Okay, first of all, I don't even KNOW of any Satanic chat rooms, and I'm intimately familiar with all the sites on theistic Satanism out there.

But yes, if you went into one and started preaching, I wouldn't be surprised if they did start cursing you, casting spells on you, and praying for your death. Satanists have a significantly lower tolerance for fundie bullshit than other groups do, for reasons I feel are obvious.

If things start flying around your room, though, you're probably on acid. Or off your meds.
